One of the most important things to look for in a roof is to check if it’s mold-free. Make sure the roof is perfectly flat and there are no curly edges or bulges. Look out for worn out spots and see if any shingles are missing. If you see such deformities in the roof then it indicates that the roof is quite old.Is metal roof cooler than shingles?
Metal reflects sunlight, keeping it cooler inside, while asphalt shingles, particularly black ones, absorb the heat of the sun, making a home that much warmer. New, white- or light-colored metal roofing with proper ventilation is better than old metal roofing, and special sealants can further cool down the material.How do you shingle a steep roof?
Secure a few brackets, slip a 2×8 or 2×10 into position on top of them, and then shingle right over the support strap as you work your way higher on the roof. The straps slide upwards off the nail heads when it’s time to move on to the next roof area, leaving no trace behind once the shingles flop back down.
